10, of in a building.

Another object of my invention is to provide a fabric structure of suchform that it will have the required stiffness, even though the mesh becomposed of relatively small gauge Wire.

Another object of my invention is to provide means for so holding abacking sheet and a wire mesh in unitary relation that the backing sh etis not likely to slip relative to the mesh, and thus result in excessiveslack in the sheet at some points relative to certain other points.

Another object of my invention is to provide a stiffening member ofgenerally channel form in cross section, and means for so holding it inthe mesh that it may be of very light material, and neverthelessprevented from flattening or collapsing under pressures that wouldordinarily cause the deformation of light weight channel members.

A further object of my invention is to provide a fabric structurewherein perforations formed in the backing sheet incidental to theattachment thereof to the mesh are sub .stantially completely closed byretaining is a rear view of the structure of Fig. 1, and v Fig. 5 is asectional view of the fabric structure on an enlarged scale.

The structure consists of a backing or form sheet 6 in front of which isplaced a wire 1930; Serial No. 455,325.

mesh'composed of What for convenience I will term strand wires 7 andstay Wires 8, and retaining bars 9 for holding the backing sheet and thewire tion.

The wires 7 and 8 are welded or otherwise i secured together at theirpoints of intersection, and the wires Shave rearWardly-extending bends10 that project through holes in the backing sheet 6, the bars 9 beingslid into position in such manner that they lie within the bends 10, andtheir forward edges abut against the rear side of the sheet 6, thuslocking the backing sheet. and the wire in unitary relation,

The fabric structures are made in sheets or rolls of convenient size andare intended to be applied to studding or other suitable framework.Plastic material 11 V such as stucco, plaster, or the like may then beapplied to imbed the reinforcing wires or rods 7- and 8, thebackingsheet 6 servingas'a form to prevent the plaster from falling awayat' the rear side of the mesh. This backing sheet may be of buildingpaper, extremely fine wire mesh or screen, or of water-proof sheetmaterial, or the like.

The retaining bars 9 are of V form in cross section and snugly fit thebends 10 so that they are accurately maintained in position with 1theiredges abutting the rear side of the sheet 6. Slit-like openings ofconsiderable length in the sheet 6 are required, to permit the bends 10to be passed through the paper, but the width of the bars 9 is such thatthe openings are substantially completely closed,'as shown more clearlyin Fig. 5, when the parts are -assembled, thus providing forsubstantially complete. support for the plastic material "throughout theface of the sheet.

It will be understood that the'bends 10 may be of various other shapes,and that the bars 9 instead of being of angular form in cross sectionmaybe of conventional channel form, or flat. In the case of fiat bars,the structure would not have as great stiffness, but said bars wouldserve to close the perforations through which the bends 10 extend.

The channel members 9 are not onlyv supported by the bends 10 in properalinement mesh mesh in assembled relawith respect to the backing sheet,but are physically supported by said bends against deformation orflattening, thus permitting the channels to be made of lighter materialthan would be the case if they were merely attached: to the structure byclips or other holding members.

Furthermore, the bends 10 are an integral part of the wire mesh, so thatthe bars 9 are. held against, slipping transversely on the rear of thesheet 6, and the sheet itself, in engaging the edges of the bars 9, isthereby better held against slipping relative to the mesh,

than if a round bar were substituted for the channel member 9. It isimportant to hold the sheet againstslippi'ng relative to the mesh sincein such event it would be so slack at some points as to require anexcessive amount of plaster in order .to imbed the mesh and at otherpoints would lie too tightly against the mesh to permit proper imbedmentof the mesh by'plaster at those points.

I claim as my invention 2- 1. Fabric structure comprising mesh formed ofwire-like members secured together at their points of intersectionandhaving rearwardly-extending bends, a backing sheet having elongatedopenings through which said bends extend, and a retaining bar of U-formin cross-section, disposed to the rear of said sheet and lying Withinsaid bends, the edges of the said bar abutting the rear side of thesheet, and the sides of the bar snugly fitting the said bends.

2. Fabric structure comprising mesh formed of wire-like members securedtogether at their points of intersection, and havingrearwardly-eXten-ding bends, a backing sheet having elongated openingsthrough which said bends extend, and a retaining bar of generallychannel form in cross section having its edges abutting the rear side ofsaid sheet and its edges snugly fitting within said bends.

, In testimony whereof, I" the said EDWARD L. BENEDICT have hereunto setmy hand.
